Atmospheric organisms are hypothetical organisms speculated to thrive within the atmosphere of Earth or other planets.

Carl SaganEdit

Carl Sagan proposed that atmospheric organisms could live in the atmosphere of a gas giant, such as Jupiter. Illustrations of atmospheric organisms have frequently appeared in books and exhibiting speculation as to the exotic forms extraterrestrial life might take. Descriptions of this sort often portray these beings as living balloons, filled with lighter than air gases. In the context of a Jupiter-like planet with a hydrogen atmosphere, such an organism would have to be a hot hydrogen balloon, since there is no other lighter gas.
